To all whom it may concern:

Be it known that l, RAYMOND Frsi-Inn, a citizen of the United Statesresiding in Philadelphia, in the county of Fhiladel hia and State ofPennsylvania, have invented certain new and useful improvements inVertically- Striped Knit Fabrics, whereof the following is aspecification, reference being had to the accompanying drawings.

My invention relates to knit fabrics of the type which are produced byknitting alternate courses of yarns differing in kind: i. e., in coloror texture. Such fabrics are well known as two-tone or heather-tonemixtures. By reason of the alternation of the two yarns they aresubstantially indistinguishable to the eye.

The object of my invention is to produce a knitfabric which will placeupon such a two-tone or heather-tone background, a vertical stripe of asolid color. While the fabric may be used for other purposes it isconvenient for me to describe it as appl ed to knit hosiery, and it isso illustrated in the accompanying drawings.

Fig. l is a view of the face of my knit fabric.

Fig. If is a view of the back of my knit fabric.

Fig. lllll is a diagrammatic side view of hosiery comprising my knitfabric; and

FiglW isa diagrammatic cross sectional view of the same along, the lineIV--l[V in Fig. lllli.

Referring to Fig. l, it will be noted that the fabric is knit of twokinds of yarn distinguished from each other by their color, and which,for the sake of convenience, Tl will speak of respectively as white andblack. Alternate courses of the said fabric are knit from differingyarns: i. e., courses, a, 0,6, g and i are knit of the white yarn, whilethe intervening courses 6, a), f and it are knit of the black yarn.' litwill also be noted that .of the wales of knitting, those numbered l 2,5, 6, 7, 8, 9, 12 and 13 are formed by the ordinary interknitting of theloops of each course with the course succeeding, thus producing for theregion of said wales, a twotone or heather-tone background; while thewales 3, a, 10 and 11 are produced by interknitting long loops of eachwhite yarn course with the similar loops of the next succeeding whiteyarn course, thus interknitting only alternate courses while the blackyarn floats unknit behind these long loops, as seen in Figs. 1 and ill.

To knit such a fabric, it'is only necessary to vary the ordinaryknittingoperation by causing the needles upon which thelong white loopsare formed to hold their loops and fail to' receive the black yarn.

By adopting the, plan of knitting which I have just explained, thebackground of the fabric is formed by the parts which are knit in theordinary way comprising multiple-wale sections and, as a'rule, themajority of the wales, and by reason of the alternation of the yarnscourse by course in these sections, the two kinds of yarn are sointermixed, as to prevent the eye from readily pickingout anddistinguishing them, thus producing the desired dominating twotoneeffect to which I have referred above. @n the other hand, the waleswhich carry the longer loops to alternating courses have the effect ofone-tone vertical stripes contrasting strongly with the background an?are composed on the face of the fabric 0 the one kind of yarn only.

lit is to be understood that any desired combination of yarns differingin color, teX- ture or other manner may be employed,- black and whitebeing merely cited by way of example,-and it is likewise to beunderstood that the background sections and stripe sections may be ofdiifering widths and proportions. But the heather-tone sections aremultiple-Wale sections and the stripe sections are narrow as comparedwith said sections. But to secure the desired effact, the two kinds ofyarn must alternate practically course by course, as otherwise the eyeis able to distinguish between the two kinds of yarn which com ose thebackground sections, and the desire heather-tone sheet is not secured.

The effect of these stripes may be en hanced by slightly varying thetension of the different yarns. in this way, the floats of the blackyarn may be drawn across behind the long loops of the white yarn withsuflicient tension to purse together the wales formed therefrom,--thuscausing the vertical stripes to protrude slightly above the face ofthefabric, as shown in Fig. IV, where 15-45 represents the protrudingvertical stripes, while 16-46 represents the sections of two-tonebackground. The striped effect which is thus secured is also illustratedAll Ati

lldfl lllltl in Fig. III whereis represented long hosiery having thecalf, ankle and top of the instep knit as I have described, theheather-tone background being shown at 1616 and the vertical stripbs15-15 standing out in sharp contrast to said background.

Having thus described my invention, I claim:

1. A vertically striped knit fabric formed of two kinds of yarnalternating course by course, the loops of succeeding courses beinginterknit along certain sections each comprising a series of adjoiningwales to form a two-tone background; the loops of the alternatingcourses of one kind of yarn being lengthened and interknit with eachother along the remaining wales; and the alternating courses of theother kind of yarn being floated behind the long interknit loops whichform the face of said Wales.

2. A vertically striped knit fabric formed of two kinds of yarnalternating course by course, the loops of succeeding courses beinginterknit along certain sections, each section comprising a relativelylarge number of adjoining wales to form a two-tone background, the loopsof the alternating courses of one kind of yarn being lengthened andinterknit with each other to form sections alternating with the firstmentioned sections and said second mentioned sections consisting of arelatively small number of wales, and the alternating courses of theother kind of yarn being floated behind the long interknit loops whichform the face of the wales of the second sections, whereby the latterdefine narrow stripes of one color contrasting with a two-tonebackground defined by the first sections.

3. A vertically striped knit fabric formed of two kinds of yarnalternating course by course, the loops of succeeding courses beinginterknit along certain multiple-Wale sections to form a two-tonebackground; the

loops of the alternating courses of one kind of yarn being lengthenedand interknit with each other along the remaining wales with the otherkind of yarn fioated behind them, the tension under which said latteryarn is knit being such as to purse together the wales formed by thelong loops causing the vertical stripes thereby formed to protrudeuponthe face of the fabric.

In testimony whereof, I have hereunto signed my name at Philadelphia,Pennsylvania. this sixteeth day of March, 1921.
